Thank you for your answer. From what i understand two tap interface can't
speak together though a bridge. so the idea is to have two veth pair
between each tap and the bridge. I should get the following topology:
Tap0 == <Veth10> == <Veth00> == bridge == <Veth01> == <Veth11> == Tap1
Now i'm not sure to understand how to connect the tap device to the Veth.
Can you give me a hint on that part ?
